Configure IPv6 PIM-SM Bootstrap Router
Configuration Conditions
Before configuring BSR, first complete the following tasks:
- Configure the network layer address of the interface, making the neighboring node network layer reachable
- Configure any unicast route protocol, making the intra-domain route reachable
- Enable the IPv6 PIM-SM protocol
Configure C-BSR
In one IPv6 PIM-SM domain, there should be the unique BSR. Multiple C-BSRs (Candidate-Bootstrap Router) elects to generate the unique BSR via the bootstrap packet.

Configure C-BSR
|
ipv6 pim bsr-candidate interface_name [ hash-mask-length [ priority-value ] ] [ vrf vrf-name ]
|
Mandatory
By default, there is no C-BSR.

- Compare the priorities. The larger the value, the higher the priority. The one with highest priority wins.
- If the priority is the same, the one with the largest IPv6 address wins.
Configure BSR Border
BSR is responsible for collecting the C-RP information and transmits the information to all devices in the IPv6 PIM-SM domain via the bootstrap packet. The BSR range is the range of the multicast domain. The bootstrap packet cannot pass the interface configured with the BSR border. The devices out of the multicast domain range cannot take part in the forwarding of the multicast service packet in the multicast domain, so as to realize the dividing of the multicast domain.
